nRF Connect for Desktop v5.0.2, programmer v4.4.1, rust-panic on startup

[gmn]

I recently purchased an nrf52840 dongle.

In nRF Connect for Desktop (v5.0.2) and with or without the device attached, Programmer (v4.4.1) starts with a rust-panic error:

This is on a w11 system.  j-link j-tag-load, rtt client, remote server, etc with v7.98b are installed. I'm not seeing python errors, but for what it's worth, v3.11 is installed. Any ideas what I have missed installing or what paths need to be updated?

Thank you!

Hi

Try running nrfutil install device=2.6.0 --force to force upgrade the nrfutil device version to 2.6.0 and see if that helps at all.

Best regards,

Simon

Simonr can the developers reproduce the error?  Any idea if it's actively being looked into yet?  Thanks!

[Simonr]

Yes, it is actively being looked into. We know about it and is looking into fixing it by releasing new app versions running on this new CLI version. They've provided a workaround that will work as well here (in case force updating nrfutil didn't work):

• Close nRF Connect for Desktop
• Set these environment variables:
  export NRF_OVERRIDE_NRFUTIL_SETTINGS=true
  export NRF_OVERRIDE_VERSION_DEVICE=2.6.1
• When updating to v2.6.1 of nRFUTIL device, you also need at least v7.94i of the J-Link drivers.
• Start nRF Connect for Desktop from the terminal having these environment variable

All apps will now use nrfutil device v2.6.1 and should work as expected.

Best regards,

Simon

Simonr - hey, baby steps, things are moving in the right direction!

1) no rust-panic and desktop is detecting nrfutil-device version 2.6.1.  woohoo!

2) The dongle is attached and in bootloader mode (1hz red led), but is not detected.  I tried programmer, quick-start, board-configurator, and bluetooth-low-energy all with no luck.

3) desktop seems to have an issue with jlink_v8.10a installed and it is expecting jlink_v7.94i

Question:  how to set the jlink version that desktop is expecting?

Here is summary from the terminal session:

// forced install:

I setup for dual boot with linux on this box and installed Debian 12.  Debian 12 also does not see the device, it does not have a rust-panic, and it also complains about the jlink version mismatch.  I -think- this will be a good testing setup because same hardware approaching from different OS.  Note this is not a linux VM, it is a whole dual boot setup.

Thank you for the help!  Now let's figure out why the device is not being detected.  I picked up parts and I think I can add a jtag header to this dongle if that would be helpful.

Simonr - an important update!  I didn't check the Saturday mail until this afternoon (Sunday) and a my second nrf52840 dongle arrived.  It -is- (woohoo!) seen by Nordic programmers on both w11 and Debian. 

So, I think the questions become:

1) how to recover from a clobbered bootloader that is in bootloader-mode (1hz red led), but that the programmer does not recognize?

2) how to tell nrf desktop to expect jlink v8 instead of v7?  Same message on both Linux and w11.

Thank you!
